PRINTING-PRESS ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 690,124, dated December31, 1901.

Application filed July 20, 1901. Serial No. 69,079. (NO model-3 T (0%whom it may concern.-

Be it known that I, FRANK C. STOCKHOLM,a citizen of the United States,residing at Philadelphia j in the county of Philadelphia and 5 State ofPennsylvania, have'invented certain new and useful Improvements inPrinting- Press Attachments, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to mechanism for sealing together adjacent sheetsof newspapers, whereby when opened for reading the papers are so markedor mutilated as to be readily detected should their return to thepublisher as unsold copies be attempted.

The invention has particular reference to certain improvements on themechanisms shown in the patents granted to L. L. Carson June 13, 1899,No. 626,965, and January 8,

1901, Reissue No. 11,881.

The primary object of the present invention is to provide an improvedpaste-receptacle and paste-delivering mechanism which are readilyremovable for the cleaning necessary at the end of each run of thepress.

A further object is to provide improved means for coupling the removablepaste-delivering mechanism with a rotating element of the press, wherebythe former is actuated.

0 In this improvement, as in the patents before referred to, the sealingmechanism is mounted on a printing-press and is designed to operate onthe webs while passing therethrough.

5 The invention consists in the novel features of construction and inthe combination and arrangement of parts hereinafter fully described andclaimed, and illustrated by the accompanying drawings, wherein Figure 1is a front elevation of mechanism embodying my improvements. Fig. 2 isan end view of the same. Fig. 3 is a cross-sectional view on line 3 3 ofFig. 1. Figs. 4, 5, and G are detail views of the paste-font. Fig. 7 isa vertical longitudinal sectional View of the font andpasting mechanism.Figs. 8, 9, 10, and 11 are detail views of font-supporting members ofthe frame.

The mechanism may be mounted on a press at any convenient point betweenthe cylinders and folder and in such position as to operate on the paperbefore the webs thereof have been superposed one upon the other. Themechanism is capable of being shifted transversely of the press, so asto operate on the web at any desired point in the width thereof, whetherat one edge or the other or between the edges, according as it may bedesired to locate the sealing-points.

Referring more particularly to the present to embodiment of myinvention, the only portions of the press which I have illustrated arethe two opposite sidebars 2 of the press-frame, to which are secured theopposite frame portions 3 and 4, carrying my improved mechanism.'Traversing the press and journaled in frames 3 and 4: are the parallelshafts 5 and 6 and adjacent the same the parallel supporting-bar 7.Shafts 5 and 6 are connected at one end by gears 5 6, and meshing withgear 6 is gear 8 on short shaft 8. This shaft is journaled in frame 3and carries gear 9,which meshes with a gear or pinion (not shown)carried by a rotating member of the press,whereby rotary motion isimparted to shafts 5 and 6.

A paste-applying roll 10 is secured to and longitudinally adjustable onshaft 6 and 00- operates with a similarly-adjustable rubberbound roll 11on shaft 5. The peripheries of rolls 10 and 11 are sufficientlyseparated to pass web 12, upon which they operate in applying the seal,as will be understood. Roll 10 is provided with a peripheral projection13 for applying paste to the under side of web 12 at each revolution ofsaid roll. The means for supplying paste to projection 13 will bepresently explained.

Depending from and supported by shaft 6 and bar 7 are the frame members14: and 15, the same being formed at their upper ends 0 with sockets toembrace the shaft and bar and be adjustable thereon, as shown. Said Thelower extremity of frame member 15 is formed with two lateral extensions18, disposed toward support 17 and preferabl in the plane thereof.

Removably positioned between frame members 14 and 15 is the paste fontor receptacle 19, having on its under side the depending foot 20, whichrests on support -17, and the slotted bottom projections 21, which bearon the lateral frame extensions 18. Said frame extensions are providedwith Vertical clamping-bolts 22, which are embraced by and secure theslotted font projections21. With the latter slotted, after theclamping-bolt nuts are slackened the font may be readily slippedlaterallyfrom between frame members 14 and 15 and entirelyremoved fromthe press.
